CICS Systems Administration

Objectives
On successful completion of this course, attendees will be able to:

• perform all CICS administration duties
• use CEDA transaction to dynamically define resources
• list the resource naming conventions
• maintain the macro coded table entries
• explain the effect parameters have on performance, reliability and availability

Who Should Attend
Those with responsibility for, or interest in, CICS administration.
Prerequisites
Prior attendance on the CICS/TS Concepts & Facilities course or equivalent experience. Special Note: attendees are encouraged to bring along the System Initialization Table macros and Overrides for a couple of production CICS regions - If Transaction Routing and/or Function Shipping is being used then a SIT and Overrides for a TOR, AOR and DOR would be welcome.
Duration
5 days
